Daughtercard Prototyping Area

Jacks/Headers/Pots

Controls Card - Jacks/Headers/Pots

• 0-6 Jacks
• 0-6 Pots
• Headers to connect to Prototyping card

J1-J6 Jacks

• Jacks have resistors on Tip/Ring-Switch
  • Typically Tip = 0 Ohm jumper, Ring/Switch = Do Not Populate (DNP on schematic)
• Tip resistors: R7, R9, R11, R13, R15, R17
• Ring/Switch resistors: R8, R10, R12, R14, R16, R18

J7 Header

• 2x8 female header

J8 Header

• 2x10 female headers

Pots

• Pots have optional pull-up/pulldown jumper positions
  • Install jumpers if pots are used as controls voltages
  • Do not install jumpers if pots are used as volume control voltages

Prototyping Daughtercard

• Controls card connections are typically male headers

J8, J28 - Pot connections

J7, J29 - Jack connections

J9 - Eurorack Power
